SeizureSense: A Wearable Epilepsy Monitoring System

Epilepsy is one of the most common chronic neurological disorders, affecting approximately 10–12 million people in India and nearly 65 million people worldwide. It is considered the fourth most common neurological condition after migraine, Alzheimer’s disease, and stroke. Epileptic seizures can cause serious health risks such as falls, head injuries, fractures, burns, breathing difficulties, and convulsive status epilepticus, creating anxiety among patients, parents, and caregivers. To address this problem, this paper proposes a wearable IoT-based seizure alert system for real-time seizure detection and emergency notification. The proposed system uses an ESP32-C3 microcontroller, MAX30102 heart rate and SpO₂ sensor, MPU6050 accelerometer and gyroscope, and an EMG sensor to monitor physiological parameters and abnormal muscle movements associated with seizures. When a seizure is detected, the device automatically sends an SMS alert with the user’s location to caregivers or family members and activates a speaker alert to notify nearby people. Prototype-level testing under controlled laboratory conditions demonstrated an estimated seizure detection accuracy of 92.5% of 5.2%, and a response time of 3–5 seconds, demonstrating that it is a reliable, real-time, and efficient solution for epilepsy monitoring.
